SUSE CVE-2026-39822

On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, 'root.Open"symlink/"' will open "symlink" even when "symlink" is a symbolic link pointing...

Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile...

GHSA-4XGF-CPJX-PC3J pydantic-settings: NestedSecretsSettingsSource follows symlinks outside secrets_dir, enabling local file read and bypassing secrets_dir_max_size

Summary NestedSecretsSettingsSource reads secret values from files in a configured secretsdir. When secretsnestedsubdir=True, a directory entry inside secretsdir that is a symbolic link pointing outside secretsdir is followed, so files outside the configured directory are read into settings value...

UBUNTU-CVE-2026-42496

Archive::Tar versions before 3.08 for Perl extract symlinks with attacker controlled targets outside the extraction directory. makespecialfile passes the tar header's linkname to symlink without validating it against absolute paths or .. segments. The secure-extract mode check that guards regular...

PT-2026-43162

Name of the Vulnerable Software and Affected Versions Archive::Tar versions prior to 3.08 Description Archive::Tar for Perl allows the extraction of symlinks with attacker-controlled targets located outside the extraction directory. The function make special file passes the tar header's linkname ...

Astra Linux – Vulnerability in php-pear

In ArchiveTar before version 1.4.14, symlinks can reference targets outside of the extracted archive. This is a separate vulnerability from CVE-2020-36193...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the ExtractRelativeToDirectoryAsync path handling in src/libraries/System.Formats.Tar/src/System/Formats/Tar/TarEntry.cs. An attacker can create a tar archive that extracts a symbolic link whose target is a roote...

golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...

CVE-2026-39861

CVE-2026-39861 affects Claude Code prior to version 2.1.64. The sandbox could be escaped by following symlinks outside the workspace when a path under a symlink was written to, allowing an unsandboxed process to reach arbitrary locations. This could enable code execution outside the sandbox under...

CVE-2026-39861 Claude Code: Sandbox Escape via Symlink Following Allows Arbitrary File Write Outside Workspace

Claude Code is an agentic coding tool. Prior to version 2.1.64, Claude Code's sandbox did not prevent sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code subsequently wrote to a path within such a symlink, its unsandboxed process followed the...

Symlink Member Name Not Validated in filter_safe_tarinfos — Symlink Created Outside Extraction Directory

Description filtersafetarinfos in keras/src/utils/fileutils.py validates member names for regular files via ispathindir line 79, but for symlink entries it only validates the link target via islinkindir line 76 — the symlink's own info.name which determines where the symlink is created on disk is...

BIT-GOLANG-2026-32282 TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix

On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the ATSYMLINKNOFOLLOW flag, which Root.Chmod uses to...
